Front-panel status LCD indicating a problem with hard drives
Action
NOTICE: This troubleshooting procedure can destroy data stored on the hard drive. Before you continue, back up all
the files on the hard drive.
1. Reboot your system and enter the SCSI configuration utility by pressing <Ctrl><h>, <Ctrl><a>, or <Ctrl><m>,
depending on your SCSI or RAID controller.
2. Ensure that the primary SCSI channel is enabled, and reboot the system.
See the documentation supplied with the controller for information on the configuration utility.
3. Verify that the device drivers are installed and configured correctly (see the operating system's documentation).
NOTE: If a drive shows signs of imminent failure, the status indicator blinks green, then amber, and then off,
repeating this sequence every two seconds. If a drive has failed, the status indicator blinks amber four times per
second.
4. Remove the hard drive and install it in the another drive bay.
5. If the problem is resolved, reinstall the hard drive in the original bay.
If the hard drive functions properly in the original bay, the drive carrier could have intermittent problems. Ensure that
the drive is properly mounted on the drive carrier (see " Installing a SCSI Hard Drive " in "Installing Drives").
If the drive carrier still does not function properly in the original bay, the SCSI backplane board has a defective
connector. See " Getting Help " for instructions on obtaining technical assistance.
6. If a RAID controller card is installed, check the SCSI cable connections inside the system:
a. Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.
b. Remove the cover (see " Removing the Cover ").
c. Check the SCSI cable connection to the RAID controller card (see the RAID controller's documentation for
detailed information).
NOTE: To operate the SCSI backplane in a 1 x 5 configuration, ensure that the SCSI backplane daughter card is
not installed. To operate the SCSI backplane in a 2x3 split configuration, ensure that the SCSI backplane
daughter card is installed (see " Installing a SCSI Backplane Daughter Card " in "Installing Drives").
d. Replace the back cover (see " Replacing the Cover ").
e. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
7. Partition and logically format the hard drive. If possible, restore the files to the drive.
To partition and logically format the drive, see the operating system documentation.
If the problem is not resolved, see " Getting Help " for instructions on obtaining technical assistance.
